COMPUTER AIDED TENSILE STRENGTH ANALYSIS OF SAILCLOTH

Thanks to its wide range of combination and design possibilities fibre reinforced composites (FRC) are considered to be material of the future. Although in the world of sailcloth such materials have come to focus almost 15 years ago their mystery is still not revealed, especially when their resistance to the forces of the wind is in question. That is also one of the reasons why, in spite of all their knowledge in aerodynamic and sail design sail-makers are still not able to make perfect sail. Last couple of years many material scientists are trying to get a better understanding of FRC materials, precisely their stress and strain principles and responses as well as fracture phenomenon. In accordance to this a lot of work is undertaking on the testing procedure` adjustments that might be helpful in exposing what actually occurs in material for the period of loading. Work presented in this paper is that type of an experiment with the goal to visually analyze manifestation of FRC sailcloth through their complete strain-stress curve.
